Traffic-related air pollution (TRAP) may affect immune responses, including those in the TH2 and TH17 pathways. To examine whether TRAP is associated with plasma level of TH17-, TH1-, and TH2-related cytokines in children with and without asthma, a cross-sectional study of 577 children (ages 6-14 years) with (n = 294) and without (n = 283) asthma in San Juan (Puerto Rico) was performed. Residen...

Digital road databases are widely used in many facets of our daily life. Most of these databases come with a nominal quality indication, but often more detailed quality descriptions regarding possible errors, the positional accuracy, and information on the completeness of the vector data are desirable. In this paper an approach for the quality description of road data from the Authoritative Top...

Most commonly, case-based reasoning is applied in domains where attribute value representations of cases are su cient to represent the features relevant to support classi cation, diagnosis or design tasks. Distance functions like the Hamming-distance or their transformation into similarity functions are applied to retrieve past cases to be used to generate the solution of an actual problem. Oft...

Worldwide, more than 185,000 children under 18 years die from road traffic accidents annually (each four minutes a child death occurred due to road crashes); with most casualties from developing countries. 95% of road traffic fatalities among children occur in developing countries. Many more children are injured, often severely, and suffering from different disabilities. Road accidents cause ex...

The surge of road pricing projects in the U.S. and around the globe over the past fifteen years has been enabled by a set of new communication and transportation technologies. There is currently a wide array of technical configurations ranging from systems based on “tried and true” shortrange radio communications to experimental systems relying on global positioning satellites. These technologi...

BACKGROUND Assessment of physical access to health services is extremely important for planning. Complex methods that incorporate data inputs from road networks and transport systems are used to assess physical access to healthcare in industrialised countries. However, such data inputs hardly exist in many developing countries. Straight-line distances between the service provider and resident p...

Greater sage-grouse (Centrocercus urophasianus) are in decline across western North America. Identifi cation of management strategies to enhance populations, such as predator management, may be needed to reduce further declines, but unintentional eff ects associated with increased human activity should also be considered. We evaluated the eff ect of 3 levels of predator management eff ort on gr...
